Question by question
A question scores 100 minus the bracket’s width as a percentage of the track, if the answer is inside it, and nothing if it is outside. The tenth-of-the-track bracket below is the one a confident player was aiming for.
- How many characters could an original tweet hold? 140 — in the lower third of its track. A bracket from 90 to 190 is a tenth of the track and scores 90; the whole track scores 0.
- How many hours are in 39 weeks? 6,552 — in the upper third of its track (a logarithmic track, so a tenth of it is a tenth of the powers of ten it spans). A bracket from 5,200 to 8,200 is a tenth of the track and scores 90; the whole track scores 0.
- How many sonnets did Shakespeare write? 154 — in the lower third of its track. A bracket from 130 to 180 is a tenth of the track and scores 90; the whole track scores 0.
- How deep is the deepest hole ever drilled, the Kola Superdeep Borehole? 7.6 miles — near the middle of its track (a logarithmic track, so a tenth of it is a tenth of the powers of ten it spans). A bracket from 6 to 9.6 is a tenth of the track and scores 90; the whole track scores 0.
- How many bones are in one human hand? 27 — in the lower third of its track. A bracket from 22.5 to 32 is a tenth of the track and scores 90; the whole track scores 0.
